:BURNER cons'rn'uc'rron non. GASOLINE icAM-B STOVES.

Application riled January i -1922. -Seria1 Nfo. 5%,620.

Briefly the invention comprises a-burnerhaving a valve, preferably cylindrical, by means of which the flow of generated gas may be regulated from full feed to closed position with a limited amount of movement. The burner carries a single spreader .plate which is formed merely byshearing to provide radial slits whichform an opening directedlaterally overthe adjacent portion of the plate in each instance. A grate positioned above the burner is supported directly by the walls of the casing within which the burner is carried.

Inthe drawings, wherein certain embodiments of the'invention are disclosed,

Fig. 1 :is a plan ofthe burner'showingj.the present valve;

Fig. 2 is a section therethrough taken on line 22 of Fig. 1;

Fig. 3 is .alongitudinal section as indicated byline 33 of Fig. '1 showing the spreader platefgrate and mounting within,

the casing;

Fig. e is a plan of the spreader plate;

Fig. 5 is'a sectional detail-on line 5 of Fig. 4;

Fig. 6 isa plan showing a modifiedform of grate mounting; and

Fig. 7 is an enlarged sectional detail of theralve showing a slight modification over that of Fig. 3.

The casing within which the burner is mounted is provided with a bottom wall 10 and side walls 12 upon any of which the grate 24c may be supported, the burner cup 14 resting'upon said bottom Wall 10. The cup 14; isprovidedwith a preferably integral manifold 15 into which gas generated from gasoline by any suitable means (not shown) is introduced for feeding into the chamber the cup. The upper edge ofjthe cup carries a spreader plate lohaving an annular flange '18 to insnreproper positioning,

the center'of thepl-atedb being depressed at to receive'the bottom of "a priming or .generating pan or cup 22 provided at the center of the grateg l. fP-latelfi is provided withnnaperture the center Ofdepress10-n20 for'the =.reception of a retaining screw '26 threaded into a boss 28 mounted upon the manifold 15 so that said plate '16 maybe securedin position. Or, as indicated Fig. 7, the depression 20 of plate "1 6 may he used directly as apriming cup.

Y :S preader plate 16 is formed by shearing, the 'sanieat .a number of places to form a plurality of radially disposed slits at '30,

the metal at one side'o'f eachslit beingforc'ed slightly out of the plane of the plate'to form slightly offset'fins '32,.bes't seen in Fig. 5 and thereby "providing elongated discharge openings or slots34 whiclrdire'ct the fuel gasv laterally overthe adjacentportions of theplate instead of directly upward as is usual. aslight swirling motion sothit'the "from any one .slot' or opening 34L will The driven'toward and'across the adjacent opening at oneside so as to insure re ignition of gas issuingtherefrom intheevent'that such should be blown out as by 'the'wind or the like. Thus it-will be impossible toblow out the entire flame on the burner except by a' very strong wind.

For the gpurpose of controlling the flow ofgas to the chamber Within the cup '14:, the manifold 15 ismacliined'toprovide a cylindrical :borewhichprovides a neat'fit for a sleeve valve 36. The upper portion of the manifold is provided with an aperture or In this manner the flame is given discharge port 35-with which a similar aperture38 in sleeve 36 is adaptedto register.

The outer end of sleeve136 also is neatly :fitted in the casting forming the cup 14: and

manifoldl5,.and is closedas by means of ,aplug 4 0 into which a stem 42,11a'ving a manipulat ng. head 44, is threaded or otherwise secured. Infthis mannerthe port 35 may be quickly opened or closed either by sliding the sleeve 36 a short distance longitudinally or by rotating it a quarter turn or less throusrh the "medium of the stem 42 which n'rojects beyond'the casing. "Within these narrow limits there is found all the range required for complete control of th burner from wide open position to eloed position. The neat fit of the sleeve within the manifold permits easy and sure adjustment to any desired position. This form, which permits adjustment by either rotation or reciprocation, is shown in Fig. 3.

In Fig. 7, a similar form is shown, but with the difference that the sleeve 36 is provided with an annular groove 45 which receives the end of the screw 26, said screw being slightly longer in this form than in the other so as to enter said groove. Thus the valve 36 may be rotated for adjustmenubut is held by the screw 26 against movement longitudinally.

The grate 2a is supported above the burner by either the side walls 12 or bottom wall 10 of the casing, and if desired the priming pan 22 may fit inthe depression 20 of the plate 16 and over the head of screw 26. As shown in Fig. 8, the means for supporting the grate 24 consists in a plurality of legs whose lower ends are shouldered for engagement with the bottom of the casing and to provide lingers which project through apertures in the bottom wall of the casing, said fingers being slightly offset or bulged at 52, if desired, so that the parts will be slightly sprung when moved into position for retaining the operative relation thereof; In the form of Fig. 6, the grate 24: is provided with a plurality of laterally extending legs also shouldered and adapted to engage the side walls 12 oi the casing, the ends of the legs having fingers to project through apertures in said walls, and the walls being sprung to permit positioning of said legs and fingers. Thus the walls of the casing itself are made to support the grate in proper position over the burner and the fingers serve as braces to strengthen the walls.

This construction is very desirable for port-able camp stoves. The grates are easily mounted upon the casing, which is of sheet metal, and may be securely retained thereby. Thus the grates may be employed either to assist in retaining or to solely retain the burner or burners, two of which are usually used. The spreader plate insures a continuously burning flame, and the valve permits quick control movement from one position v to another. The spreader plate also has adsaid plate having a central depression and being inwardly flanged at its outer edge to engage the upper edge of the wall of the cup, the Zone between the depression and the flange having a multiplicity of radial slots, the material of the plate being oll'set outwardly adj acent the slots to form lips for directing the flame laterally.

2. A gas burner comprising a burner cup and a spreader plate, the latter having a central depression and an inwardly projecting flange at its outer edge where it engages the cup, the zone between the depression and the flange having. a plurality of radial slots, the material of the plate being offset outwardly adjacent the slots to form lips for directing the flame laterally, the slots being of uniform width throughout their length.

8. A spreader plate having a central depression and being inwardly flanged at its outer edge in the direction of the depression, the zone between the depression and the flange having a multiplicity of radial slots. the material of the plate being oilset outwardly adjacent the slots to form lips for directing the flame laterally.

4. A burner for camp stoves, having a cup and a spreader plate mounted thereon, said plate having a central depression and being inwardly flanged at its outer edge to engage the upper edge of the wall. of the cup, the Zone between the depression and the flange having a plurality of radial slits, the material oi the plate being offset outwardly adjacent one side of said slits to form slots, the width of said slots being equal along their entire length.

5. A burner for camp stoves having a cup and spreader plate, the plate having a central depression and having its outer edges inwardly flanged a plurality of? radially disposed elongated openings formed by shearing the plate and offsetting the same at one side only of each opening so as to retain all the stock of the plate adjacent said openings, each opening being of uniform width and the offset edges being all in the same plane.

6. A burner for camp stoves comprising a burner cup, a spreader plate secured thereto, said plate having a depression, a grate above said plate and having a depend ing member positioned in said depression. and legs on the grate for supporting the same independently of the cup and plate.

In testimony whereof, we aflix our sig natures.
